ZF 635501919 – Tapered Roller Bearing 65×120×33 mm for ZF Marine Transmissions

The ZF 635501919 Tapered Roller Bearing is a high-precision component engineered for marine propulsion systems, ZF transmissions, and heavy-duty gearboxes. With a 65×120×33 mm profile, this bearing is built from SAE 52100 heat-treated steel, delivering superior load capacity, wear resistance, and operational stability under radial and axial loads. Ideal for harsh marine environments, it supports speeds up to 4500 RPM with oil lubrication and features C3 clearance for high-speed operation with reduced friction and heat generation.

Key Features:

Tapered roller design for handling both radial and axial loads
Manufactured from SAE 52100 high-strength bearing steel
Dynamic load rating: 115 kN, static load rating: 95 kN
Supports high-speed rotation up to 4500 RPM (oil) / 3500 RPM (grease)
C3 clearance optimized for thermal expansion and high-speed operation
Open design for efficient lubrication flow
Corrosion-resistant surface treatment for marine conditions
